constexpr decltype(auto) operator*(); | (1) | (since C++20)

constexpr auto operator->() const noexcept requires std::contiguous_iterator<I>; | (3) | (since C++20)

1,2) Returns a reference to the current element. The behavior is undefined if this->count() <= 0. The function's body is equivalent to return *current;.
3) Returns a pointer to the current element. The function's body is equivalent to return std::to_address(current);.

### Parameters

(none)

### Return value

Reference or pointer to the current element.

### Example

Run this code

    #include <complex>
    #include <iostream>
    #include <iterator>
    using std::operator""i;

    int main()
    {
        const auto il = {1.i, 2.i, 3.i, 4.i, 5.i};

        for (std::counted_iterator i{il.begin() + 1, 3}; i != std::default_sentinel; ++i)
            std::cout << *i << ' ';
        std::cout << '\n';

        for (std::counted_iterator i{il.begin() + 1, 3}; i != std::default_sentinel; ++i)
            std::cout << i->imag() << ' ';
        std::cout << '\n';
    }

Output:

    (0,2) (0,3) (0,4)
    2 3 4
